Abstract: A golf training device which clamps onto the shaft of a standard golf club. The device has a holding block which holds a laser pointing in a downward direction. A hinged mirror at the light emitting end of the laser causes the laser light to be reflected at roughly a ninety degree angle and thereby run parallel to the ground.
